# pattern-matching

@shikasd Awesome work so far! One thought I had was on the "marking" of the expression to match. So as @raulraja pointed out, we've got case synthetic to act as a marker. In the current iteration, it's looking at when subject, but we would also need to handle the expression when it's not a when subject or even outside when entirely. For example:

val matt = Person("Matt", "Moore")
val Person(_, lastName) = matt

Another example would be for matching on lists (though that's not quite in scope just yet, as there's more stuff to solve there).

I'll be able to experiment more with this tonight. Of course, I'm still new to the internal APIs so having your help, Raul's help, and everyone else on that has been a tremendous boost to this effort. So thank you for that! 🙂 If I'm able to figure out how to generalize the current version without when expressly (so it'll work in more general cases) I'll push some code up. Unless you beat me to it 😉

Thanks @Rachel for looking into 1.4. I'm very eager to see 1.4 be finally ready, as I'm sure all of you are as well 🙂

Of course, I realize that the example I listed above for destructuring with the value assignment does not have case so that might be another scenario where we need to use case - unless we can find another way to mark that out.

Note that it is something Kotlin does not parse by default:

Ah yes. I think there may have been some other syntax we figured out. I think we had this discussion earlier in this channel.
